Actually the upgrade is a monstrosity and it should be removed...
The upgrade is perfectly fine.
Can we please remove Ostheer's scope?
No
But now, the 75mm Sherman has a target size advantage, making a powerful upgrade even better.
If the 76mm M4 isn't picked it's not because of the 75mm going from 22 target size to 20.
If 34/85 is such powerful tank, why we never see it?
T34/85s are amongst the best mediums in the game, they're getting a target size buff, and Guard Motor is quite popular in 1v1. They are not a rare sight.
25% capture rate is reasonable in the late game. IS have the same bonus from the very start of the game and I have never seen anyone complain about it.
How dare you state the obvious? 4 man Ostheer squads definitely have the same capping power as Soviet 6man Weapon crews and 7man Cons with merge. Source: Stuff
I think the Sherman Dozer upgrade should raise target size back to 23.
Additionally, it should remove the hull mg, as it currently shoots through the blade.
And I think P4s should shoot nukes. Source: Stuff
